CORTECO 19016583 Dimensions

The principal dimensions are:

Inside Diameter: 55 mm
Outside Diameter: 74 mm
Height 1: 6 mm
Height 2: 9.2 mm
Complete Size: 55x74x6/9.2 mm

For this product, both height values are important.

The specification should not be simplified to 55x74x6 mm, because the additional 9.2 mm value is part of the complete product geometry.

A seal with the same 55 mm and 74 mm nominal diameters but a different profile should not automatically be considered technically equivalent.

NBR Material

CORTECO 19016583 is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing applications involving many mineral oils, greases and lubricants.

Actual suitability depends on the operating medium, temperature, shaft speed and other working conditions.

No product-specific temperature range, pressure limit or maximum shaft speed should be assigned to CORTECO 19016583 without corresponding manufacturer documentation.

KBW Seal Design

The confirmed CORTECO design designation is:

KBW

The most precise technical identification is:

CORTECO 19016583 NBR KBW 55x74x6/9.2

The KBW code is an important part of the product specification and should be retained when comparing possible replacements.

Detailed lip geometry or directional sealing characteristics should not be inferred from the KBW code alone without product-specific CORTECO documentation.

Mazda OE H260-33-065

The Mazda OE reference corresponding to CORTECO 19016583 is:

MAZDA H260-33-065

Alternative format:

H26033065

This OE reference is cross-referenced to CORTECO 19016583B in aftermarket catalogues.

For OE-based identification, the preferred comparison sequence is:

Mazda H260-33-065 -> CORTECO 19016583 -> 55x74x6/9.2 mm -> NBR -> KBW

Mazda Wheel Hub Shaft Seal

CORTECO 19016583B is classified in TecDoc-derived aftermarket data as a:

Shaft Seal, wheel hub

This means the product is associated with a wheel hub sealing position in selected Mazda applications.

The product may therefore be searched as:

Mazda wheel hub oil seal
Mazda wheel hub shaft seal
Mazda H26033065 oil seal
Mazda H260-33-065 seal
CORTECO 19016583 Mazda
CORTECO 19016583B wheel hub seal

The exact installation position should still be checked in the vehicle or OE catalogue.

Selected Mazda 929 III Application

Application catalogues list CORTECO 19016583B for selected Mazda 929 III (HC) configurations, including late-1980s and early-1990s vehicles.

However, model name and year alone are not sufficient for accurate replacement selection.

The exact application depends on axle, hub and vehicle configuration.

The preferred identification sequence remains:

Mazda OE -> CORTECO reference -> complete dimensions -> material -> KBW design

CORTECO 19016583 and 19016583B

The product may be encountered under:

CORTECO 19016583
CORTECO 19016583B

The dimensional CORTECO catalogue uses the reference 19016583, while TecDoc and aftermarket catalogues often use the B-suffixed reference.

The trade reference associated with the product is:

82016583

Both CORTECO number formats are useful for technical search and product identification.

Selection and Interchangeability

When selecting a replacement for CORTECO 19016583, verify:

• CORTECO reference 19016583 / 19016583B
• inside diameter 55 mm
• outside diameter 74 mm
• height 1: 6 mm
• height 2: 9.2 mm
• complete size 55x74x6/9.2 mm
• NBR material
• KBW design
• Mazda OE H260-33-065 / H26033065
• exact wheel hub installation position

A generic 55x74 mm oil seal should not automatically be considered fully interchangeable with CORTECO 19016583.

The complete 6/9.2 mm profile, KBW design and OE reference are important for correct replacement selection.
